Methods of applying glutinous substances

ABSTRACT

A method of delivering a glutinous substance from a cartridge to a brush comprises receiving the cartridge inside a sleeve through an inlet of the sleeve while a pressure cap, located proximate the inlet of the sleeve, is in an open position. The method also comprises moving the pressure cap, located proximate the inlet of the sleeve, into a closed position to sealingly couple the pressure cap with a trailing end of the cartridge and to sealingly couple a valve with a leading end of the cartridge. The method further comprises applying pressure to the glutinous substance in the cartridge through a pressure input of the pressure cap to urge the glutinous substance from the cartridge to the valve. The method additionally comprises rotating the brush and opening the valve to enable the glutinous substance to flow from the valve to the brush at least when the brush is rotating.

Illustrative, non-exhaustive examples, which may or may not be claimed,of the subject matter according the present disclosure are providedbelow.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.2-6, apparatus 102 for delivering glutinous substance 168 from cartridge166 to brush 298 is disclosed. Apparatus 102 comprises sleeve 106,comprising central axis 121, inlet 124, and outlet 128 opposite inlet124. Sleeve 106 is configured to receive cartridge 166 through inlet124. Apparatus 102 also comprises pressure-cap assembly 104, coupled tosleeve 106. Pressure-cap assembly 104 comprises pressure cap 110,proximate inlet 124 of sleeve 106. With cartridge 166 received withinsleeve 106, pressure cap 110 is movable between, inclusively, a closedposition, in which pressure cap 110 is in sealed engagement withtrailing end 169 of cartridge 166, and an open position, in whichpressure cap 110 provides clearance sufficient for insertion ofcartridge 166 inside sleeve 106 through inlet 124. Pressure cap 110comprises pressure input 118, selectively operable to apply pressure toglutinous substance 168 in cartridge 166 when cartridge 166 is receivedwithin sleeve 106, pressure cap 110 is in the closed position, andleading end 167 of cartridge 166 is in sealed engagement with valve 154.Pressure-cap assembly 104 also comprises actuator 114, coupled topressure cap 110 and to sleeve 106. Actuator 114 is selectively operableto move pressure cap 110 relative to sleeve 106 between, inclusively,the closed position and the open position. Additionally, apparatus 102comprises valve interface 108, proximate outlet 128 of sleeve 106. Valveinterface 108 is configured to be coupled with valve 154. Apparatus 102further comprises brush-arm assembly 176, coupled to sleeve 106.Brush-arm assembly 176 is configured to retain brush 298 and is capableof rotating brush 298. Valve 154 is selectively operable, when thepressure is applied to glutinous substance 168 in cartridge 166, toenable glutinous substance 168 to flow from cartridge 166 to brush 298at least when brush-arm assembly 176 rotates brush 298. The precedingsubject matter of this paragraph characterizes example 1 of the presentdisclosure.

Apparatus 102 is configured to facilitate a reduction in the labor,time, and inaccuracies associated with the application of glutinoussubstances onto surfaces of workpieces. Cartridge 166 of apparatus 102provides modular containment of glutinous substance 168. Sleeve 106 ofapparatus 102 enables a secure coupling of cartridge 166 to apparatus102. Pressure-cap assembly 104 allows both access to sleeve 106 for theinsertion of cartridge 166 into sleeve 106 and the application ofpressure to cartridge 166 for urging glutinous substance 168 out ofsleeve 106. Actuator 114 facilitates automated actuation of pressure-capassembly 104. Valve interface 108 enables secure attachment of valve 154to apparatus 102 and quick release of valve 154 from apparatus 102. Withcartridge 166 received within sleeve 106 and pressure cap 110 in aclosed position, cartridge 166 is sealed with valve 154 to enable sealedflow of glutinous substance 168 from cartridge 166 to valve 154 via theapplication of pressure to glutinous substance 168 in cartridge 166.Brush-arm assembly 176 enables rotation of brush 298 and facilitatesdelivery of glutinous substance 168 to brush 298 while brush 298 isrotating.

Apparatus 102 can include pressure tubes 138 to facilitate thecommunication of pressure to and from various components of apparatus102. For example, pressure tubes 138 may communicate pressure topressure inputs 118. As an example, pressure tubes 138 may communicatepressure to and from actuator 114 to facilitate selective operation ofactuator 114. Also, pressure tubes 138 may communicate pressure topressure inputs 130 to control operation of valve 154, such as openingand closing of valve 154.

In some examples, various components of apparatus 102 are fixed tosleeve 106 via clamps 116, 132. For example, actuator 114 is fixed tosleeve 106 by clamp 116 and valve interface 108 is fixed to sleeve 106by tube 194 secured about sleeve 106 by clamp 132. According to otherexamples, the various components of apparatus 102 are fixed to sleeve106 using other fixation techniques, such as fastening, adhering,co-forming, and the like.

Actuator 114 can be any of various actuators known in the art, such aslinear actuators and rotary actuators, powered in any of various ways,such as pneumatically, electromagnetically, electrically, hydraulically,and the like. Pressure inputs 118, 130 can be pneumatic fittings in someexamples. As used herein, a central axis of an object is a longitudinalsymmetry axis of the object.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.2, 4, 6, and 7, pressure input 118 of pressure cap 110 is selectivelypneumatically operable. The preceding subject matter of this paragraphcharacterizes example 2 of the present disclosure, wherein example 2also includes the subject matter according to example 1, above.

Selective pneumatic operation of pressure input 118 of pressure cap 110enables precise application of pneumatic pressure to glutinous substance168 in cartridge 166 to precisely control the flow of glutinoussubstance 168 out of cartridge 166 and into valve 154. Moreover,selective pneumatic operation of pressure input 118 of pressure cap 110facilitates the use of automated pneumatic controls to control thepneumatic operation of pressure input 118 of pressure cap 110.

Referring generally to FIGS. 1A AND 1B and particularly to, e.g., FIG.7, pressure cap 110 further comprises gasket 111, configured to form aseal between pressure cap 110 and interior surface 113 of cartridge 166when pressure cap 110 is in the closed position and valve 154 isretained by valve interface 108. The preceding subject matter of thisparagraph characterizes example 3 of the present disclosure, whereinexample 3 also includes the subject matter according to any one ofexamples 1 or 2, above.

Gasket 111, by forming seal between pressure cap 110 and interiorsurface 113 of cartridge 166, facilitates the containment of pressurefrom pressure input 118 of pressure cap 110 to within cartridge 166.

Gasket 111 can be an O-ring made from a pliable or compressiblematerial, such as rubber, silicone, and plastic polymers.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIG.2, pressure-cap assembly 104 further comprises arm 115, pivotable aboutaxis 117 that is fixed relative to sleeve 106 and is perpendicular tocentral axis 121 of sleeve 106. Pressure cap 110 is coupled with arm115. The preceding subject matter of this paragraph characterizesexample 4 of the present disclosure, wherein example 4 also includes thesubject matter according to any one of examples 1-3, above.

Arm 115, being pivotable about axis 117 that is fixed relative to sleeve106 and is perpendicular to central axis 121 of sleeve 106, enablespressure cap 110 to be moved between the closed position, to sealinglyengage trailing end 169 of cartridge 166, and the open position, toprovide clearance sufficient for insertion of cartridge 166 insidesleeve 106 through inlet 124 of sleeve 106 and ejection of cartridge 166from sleeve 106. In other words, arm 115 allows pressure cap 110 to bepivoted into sealed engagement with cartridge 166 and pivoted away fromcartridge 166 to allow cartridge 166 to be inserted into or removed fromsleeve 106.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.2-4 and 6, pressure-cap assembly 104 further comprises lock mechanism112, mechanically coupling arm 115 with actuator 114. Lock mechanism 112is configured to releasably lock pressure cap 110 in the closed positionby releasably locking arm 115 relative to sleeve 106. The precedingsubject matter of this paragraph characterizes example 5 of the presentdisclosure, wherein example 5 also includes the subject matter accordingto example 4, above.

Using lock mechanism 112 to releasably lock pressure cap 110 in theclosed position by releasably locking arm 115 relative to sleeve 106prevents disengagement between pressure cap 110 and cartridge 166 shouldactuator 114 fail. In other words, in the event actuator 114 fails tourge pressure cap 110 in closed position, such as due to loss ofpressure to or malfunction of actuator 114, while pressure is applied toglutinous substance 168 in cartridge 166, lock mechanism 112 lockspressure cap 110 in the closed position to prevent pressure withincartridge 116 from inadvertently moving pressure cap 110 out of theclosed position.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.2-4 and 6, actuator 114 is selectively operable to move lock mechanism112 between, inclusively, a locked position, in which arm 115 isreleasably locked relative to sleeve 106 so pressure cap 110 isreleasably locked in the closed position, and an unlocked position, inwhich arm 115 is arranged relative to sleeve 106 so that pressure cap110 is in the open position. The preceding subject matter of thisparagraph characterizes example 6 of the present disclosure, whereinexample 6 also includes the subject matter according to example 5,above.

Actuator 114 is configured to enable lock mechanism 112 to unlockpressure cap 110 and allow pressure cap 110 to move out of the closedposition by moving lock mechanism 112 relative to arm 115, via selectiveoperation of actuator 114, while pressure cap 110 is sealingly engagedwith cartridge 166. In other words, lock mechanism 112 in the lockedposition will lock pressure cap 110 in the closed position untilactuator 114 moves lock mechanism 112 relative to pressure cap 110 tounlock lock mechanism 112 and move pressure cap 110 into the openposition.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.2-4 and 6, actuator 114 is pneumatically operable. When lock mechanism112 is in the locked position, lock mechanism 112 remains in the lockedposition if actuator 114 loses pressure. The preceding subject matter ofthis paragraph characterizes example 7 of the present disclosure,wherein example 7 also includes the subject matter according to example6, above.

In the event actuator 114 loses pressure, while pressure is applied toglutinous substance 168 in cartridge 166, lock mechanism 112 lockspressure cap 110 in the closed position to prevent pressure withincartridge 116 from inadvertently moving pressure cap 110 out of theclosed position.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., 2-4and 6, lock mechanism 112 comprises an over-center linkage. Thepreceding subject matter of this paragraph characterizes example 8 ofthe present disclosure, wherein example 8 also includes the subjectmatter according to any one of examples 5-7, above.

The over-center linkage of lock mechanism 112 enables quick, easy, andeffective locking and unlocking of the lock mechanism.

The over-center linkage can be a passive lock mechanism that is simplyconstructed, yet effective at preventing backdriving. For example, theover-center linkage includes first and second linkages eachindependently pivotable about the same first axis. The first linkage ispivotally fixed to arm 115 and pivots about a second axis. The secondlinkage is pivotally fixed relative to sleeve 106 and pivots about athird axis. As arm 115 rotates to move pressure cap 110 toward closedposition, the first linkage rotates about the first axis in a firstrotational direction and the second linkage rotates about the first axisin a second rotational direction opposite the first rotational directionuntil the first, second, and third axes are aligned, which positions theover-center linkage in an over-center position. Further rotation of arm115 to move pressure cap 110 into the closed position results in theover-center linkage moving beyond the over-center position, which locksarm 115 and prevents arm 115 from rotating pressure cap 110 toward theopen position. The over-center linkage is unlocked to allow arm 115 torotate pressure cap 110 toward the open position by concurrentlypivoting, via actuator 114, the first linkage about the first axis inthe second rotational direction and pivoting the second linkage aboutthe first axis in the first rotational direction until the over-centerlinkage moves into and beyond the over-center position.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIG.2, pressure cap 110 is pivotable relative to arm 115. Pressure-capassembly 104 further comprises biasing element 122, configured totorsionally bias pressure cap 110 relative to arm 115. The precedingsubject matter of this paragraph characterizes example 9 of the presentdisclosure, wherein example 9 also includes the subject matter accordingto any one of examples 4-8, above.

Because arm 115, to which pressure cap 110 is coupled, rotates to movepressure cap 110 into the closed positioned, in sealed engagement withtrailing end 169 of cartridge 166, enabling pressure cap 110 to pivotrelative to arm 115 allows pressure cap 110 to maintain coaxialalignment with trailing end 169 of cartridge 166 as arm 115 rotates. Bytorsionally biasing pressure cap 110, biasing element 122 ensurespressure cap 110 is coaxially aligned with trailing end 169 of cartridge166 as pressure cap 110 initially engages trailing end 169 of cartridge166. In this manner, pressure cap 110 can properly engage and seatwithin trailing end 169 of cartridge 166 without binding with orcrookedly entering trailing end 169 of cartridge 166. As used herein, to“torsionally bias” means to continuously apply a moment, which may ormay not have a constant magnitude, but is always applied in the samedirection and has a magnitude greater than zero.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIG.2, biasing element 122 comprises a torsion spring. The preceding subjectmatter of this paragraph characterizes example 10 of the presentdisclosure, wherein example 10 also includes the subject matteraccording to example 9, above.

A torsion spring facilitates a passive and simple way to torsionallybias pressure cap 110 relative to arm 115.

The torsion spring can be coupled at one end to arm 115 and at anotherend to pressure cap 110. In some examples, the torsion spring includes acoiled or twisted torsion bar that biases one end of the torsion springrelative to the other end of the torsion spring.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIG.5, apparatus 102 further comprises control valve 181 that ispneumatically coupled to pressure input 118 of pressure cap 110 and toactuator 114. Control valve 181 is configured to disable operation ofactuator 114 by preventing pressure from being communicated to actuator114 to disable operation of actuator 114 when, with pressure cap 110 inthe closed position, pressure is applied to glutinous substance 168 incartridge 166 through pressure input 118. The preceding subject matterof this paragraph characterizes example 11 of the present disclosure,wherein examplell also includes the subject matter according to any oneof examples 1-10, above.

Control valve 181 prevents actuator 114 from inadvertently openingpressure cap 110 while pressure is being applied to glutinous substance168 in cartridge 166 through pressure input 118. Preventing pressure cap110 from opening while pressure is being applied to glutinous substance168 due to inadvertent actuation of actuator 114 ensures pressure withincartridge 166 is not inadvertently released.

In some examples, control valve 181 is a two-way, normally open,air-piloted valve manufactured by Clippard Instrument Laboratory, Inc.of Cincinnati, Ohio.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.2 and 7, apparatus 102 further comprises pressure sensor 158, configuredto be coupled to valve 154. The preceding subject matter of thisparagraph characterizes example 12 of the present disclosure, whereinexample 12 also includes the subject matter according to any one ofexamples 1-11, above.

Pressure sensor 158 enables detection of the pressure of glutinoussubstance 168 in valve 154. The pressure of glutinous substance 168 invalve 154 detected by pressure sensor 158 can be used to control therate at which glutinous substance 168 flows from cartridge 166 to valve154. Additionally, the pressure of glutinous substance 168 in valve 154detected by pressure sensor 158 can be used to control valve 154 toregulate the rate at which glutinous substance 168 flows from valve 154to brush 298. Further, pressure sensor 158 being configured to becoupled to valve 154 allows pressure sensor 158 to remain part ofapparatus 102 while being decoupleable from valve 154 to remove valve154 from apparatus 102 or being coupleable to valve 154 after valve 154is coupled to apparatus 102.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.2 and 4-6, apparatus 102 further comprises pressure-signal conditioner144, electrically coupled to pressure sensor 158. The preceding subjectmatter of this paragraph characterizes example 13 of the presentdisclosure, wherein example 13 also includes the subject matteraccording to example 12, above.

Pressure-signal conditioner 144 enables communication ofpressure-related information from pressure sensor 158 to controller 157in a format useable by controller 157. Accordingly, pressure-signalconditioner 144 provides data format conversion functionality on-boardapparatus 102, rather than at controller 157.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.5 and 7, valve interface 108 comprises receptacle 182 that iscross-sectionally complementary to receptacle interface 198 of valve154.

In one example,retainer 184 is a disk-like element that is rotatable to orient retainer184 between the at least one retainer orientation and the at least onereleasing orientation.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS.5 and 7, receptacle interface 198 of valve 154 comprises receiver 199,configured to receive and sealingly engage leading end 167 of cartridge166. The preceding subject matter of this paragraph characterizesexample 74 of the present disclosure, wherein example 74 also includesthe subject matter according to any one of examples 70-73, above.

Reception of leading end 167 of cartridge 166 in receiver 199 ofreceptacle interface 198 of valve 154 and sealing engagement of leadingend 167 of cartridge 166 in receiver 199 of receptacle interface 198 ofvalve 154 ensures glutinous substance 168 does not leak from interfacebetween leading end 167 of cartridge 166 and valve 154 as glutinoussubstance 168 flows from cartridge 166 to valve 154.

Referring generally to, e.g., FIGS. 1A-6 and particularly to FIG. 13A,method 300 of delivering glutinous substance 168 from cartridge 166 tobrush 298 is disclosed. Method 300 comprises (block 302) receivingcartridge 166 inside a sleeve 106 through inlet 124 of sleeve 106 whilepressure cap 110, located proximate inlet 124 of sleeve 106, is in anopen position. Cartridge 166 has leading end 167 and trailing end 169.Method 300 also comprises (block 304) moving pressure cap 110, locatedproximate inlet 124 of sleeve 106, into a closed position to sealinglycouple pressure cap 110 with trailing end 169 of cartridge 166 and tosealingly couple valve 154 with leading end 167 of cartridge 166. Method300 further comprises (block 306) applying pressure to glutinoussubstance 168 in cartridge 166 through pressure input 118 of pressurecap 110 to urge glutinous substance 168 from cartridge 166 to valve 154.Method 300 additionally comprises (block 308) rotating brush 298. Also,method 300 comprises (block 310) opening valve 154 to enable glutinoussubstance 168 to flow from valve 154 to brush 298 at least when brush298 is rotating. The preceding subject matter of this paragraphcharacterizes example 75 of the present disclosure.

Method 300 facilitates a reduction in the labor, time, and inaccuraciesassociated with the application of glutinous substances onto surfaces ofworkpieces. Cartridge 166 provides modular containment of glutinoussubstance 168. Sleeve 106 enables a secure coupling of cartridge 166relative to valve 154. Movement of pressure cap 110 between the openposition and closed position allows both access to sleeve 106 for theinsertion of cartridge 166 into sleeve 106 and the application ofpressure to cartridge 166 for urging glutinous substance 168 out ofsleeve 106. With cartridge 166 received within sleeve 106 and pressurecap 110 in a closed position, cartridge 166 is sealed with valve 154 toenable sealed flow of glutinous substance 168 from cartridge 166 tovalve 154 via the application of pressure to glutinous substance 168 incartridge 166. Opening valve 154 to enable glutinous substance 168 toflow from valve 154 to brush 298 facilitates the delivery of glutinoussubstance 168 to surface 172 of workpiece 170 through brush 298 whilebrush 298 is rotating.

Referring generally to, e.g., FIGS. 1A-6 and particularly to FIG. 13A,according to method 300, (block 312) pressure cap 110 is pivotallycoupled to arm 115. Moving pressure cap 110 into the closed positioncomprises (block 314) rotating arm 115 in a first rotational directionabout axis 117. Axis 117 is fixed relative to sleeve 106 andperpendicular to central axis 121 of sleeve 106. The preceding subjectmatter of this paragraph characterizes example 76 of the presentdisclosure, wherein example 76 also includes the subject matteraccording to example 75, above.

Arm 115, being pivotable about axis 117 that is fixed relative to sleeve106 and is perpendicular to central axis 121 of sleeve 106, enablespressure cap 110 to be moved between the closed position, to sealinglyengage trailing end 169 of cartridge 166, and the open position, toprovide clearance sufficient for insertion of cartridge 166 insidesleeve 106 through inlet 124 of sleeve 106 and ejection of cartridge 166from sleeve 106. In other words, arm 115 allows pressure cap 110 to bepivoted into sealed engagement with cartridge 166 and pivoted away fromcartridge 166 to allow cartridge 166 to be inserted into or removed fromsleeve 106.

Referring generally to, e.g., FIGS. 1A-6 and particularly to FIG. 13A,according to method 300, moving pressure cap 110 into the closedposition comprises (block 316) torsionally biasing pressure cap 110relative to arm 115. The preceding subject matter of this paragraphcharacterizes example 77 of the present disclosure, wherein example 77also includes the subject matter according to example 76, above.

Because arm 115, to which pressure cap 110 is coupled, rotates to movepressure cap 110 into the closed positioned, in sealed engagement withtrailing end 169 of cartridge 166, enabling pressure cap 110 to pivotrelative to arm 115 allows pressure cap 110 to maintain coaxialalignment with trailing end 169 of cartridge 166 as arm 115 rotates. Bytorsionally biasing pressure cap 110, biasing element 122 ensurespressure cap 110 is coaxially aligned with trailing end 169 of cartridge166 as pressure cap 110 initially engages trailing end 169 of cartridge166. In this manner, pressure cap 110 can properly engage and seatwithin trailing end 169 of cartridge 166 without binding with orcrookedly entering trailing end 169 of cartridge 166.

Releasably locking pressure cap 110 in the closed position preventsdisengagement between pressure cap 110 and cartridge 166 should actuator114 fail. In other words, in the event actuator 114 fails to urgepressure cap 110 in closed position, such as due to loss of pressure toor malfunction of actuator 114, while pressure is applied to glutinoussubstance 168 in cartridge 166, releasably locking pressure cap 110 inthe closed position prevents pressure within cartridge 116 frominadvertently moving pressure cap 110 out of the closed position.

Referring generally to, e.g., FIGS. 1A-4 and 6 and particularly to FIGS.13A and 13B, according to method 300, moving pressure cap 110 into theclosed position comprises (block 318) pneumatically causing actuator 114to have a first length. Actuator 114 is coupled to pressure cap 110.Releasably locking pressure cap 110 in the closed position comprises(block 324) mechanically locking pressure cap 110 in the closedposition. The preceding subject matter of this paragraph characterizesexample 79 of the present disclosure, wherein example 79 also includesthe subject matter according to example 78, above.

Actuator 114 facilitates automated movement of pressure cap 110 into theclosed position. Mechanically locking pressure cap 110 in the closedposition provides a secure and reliable way to prevent disengagementbetween pressure cap 110 and cartridge 166 should actuator 114 fail.

Referring generally to, e.g., FIGS. 1A-4 and 6 and particularly to FIG.13A, according to method 300, (block 326) lock mechanism 112 is used tomechanically lock pressure cap 110 in the closed position. When lockmechanism 112 is in a locked position, (block 326) lock mechanism 112remains in the locked position if actuator 114 loses pressure. Thepreceding subject matter of this paragraph characterizes example 80 ofthe present disclosure, wherein example 80 also includes the subjectmatter according to example 79, above.

Using lock mechanism 112 to mechanically lock pressure cap 110 in theclosed position prevents disengagement between pressure cap 110 andcartridge 166 should actuator 114 fail. In other words, in the eventactuator 114 fails to urge pressure cap 110 in closed position, such asdue to loss of pressure to or malfunction of actuator 114, whilepressure is applied to glutinous substance 168 in cartridge 166, lockmechanism 112 locks pressure cap 110 in the closed position to preventpressure within cartridge 116 from inadvertently moving pressure cap 110out of the closed position.
